I think its very disingenuous to not understand both sides of the Ethan Klein vs iDubbbz lawsuit.
Ethan is absolutely breaking the internet "golden rule" by moving this into IRL action. This does set a bad precedent among creators who beef with each other going forward, especially when Ian didn't even create the disturbing claim - just rebroadcasted it in the most bad faith way possible. Its not kosher (pun may or may not be intended) to be the guy who makes a mountain out of a molehill.
However, I do understand that this has gone beyond just internet drama for Ethan - its reached inside his home. If I were in his shoes I'd think "what kind of man, husband, or father would I be if I didn't do everything in my power to protect my family?" Especially when the person amplifying the message has been in your home and met your family as a former friend.
Again, choosing a side is reasonable. You're probably inclined one way or the other depending on your own experiences, but completely invalidating the opposing sentiment is clearly disingenuous and gives off big "team sports".
Im personally against the lawsuit, I dont think it shouldve gone beyond a C&D, but I can understand where Ethan is coming from - even if it does break the golden rule.
